| In order evaluate digestible lysine levels in diets supplemented with 20 ppm of ractopamine on the performance and carcass traits, 64 barrows with high genetic potential at finishing phase were allotted in a completely randomized block design with four digestible lysine levels (0.80, 0.90, 1.00, and 1.10%), eight replicates and two pigs per experimental unit. Initial body weight and pigs' kinship were used as criteria in the blocks formation. Diets were mainly composed of corn and soybean meal supplemented with minerals, vitamins and amino acids to meet pigs' nutritional requirements at the finishing phase, except for digestible lysine. No effect of digestible lysine levels was observed in animal performance. The digestible lysine intake increased linearly... |

| Este estudo foi conduzido com o objetivo de avaliar os níveis de fitase em rações para suínos em crescimento selecionados para deposição de carne. Foram utilizados 64 suínos mestiços (32 machos castrados e 32 fêmeas), híbridos comerciais, com peso médio inicial de 23,311±2,254 kg, distribuídos em delineamento de blocos casualizados, com quatro tratamentos, oito repetições e dois animais (um macho e uma fêmea) por unidade experimental. Os tratamentos foram constituídos por uma ração controle de origem vegetal, sem inclusão de fosfato bicálcico e fitase, contendo 0,100% de fósforo disponível; e de outras três rações obtidas pela inclusão de 300, 600 e 1200 unidades de fitase (UFT kg-1) à ração controle. Os níveis de fitase influenciaram de forma linear o... |

| ABSTRACT: To evaluate the effect of supplementation with mannan oligosaccharides, avilamycin and halquinol, alone or in combination, on the performance, carcass characteristics and antibody production in broilers (1-49 days old), male broiler chicks (n=1440; Cobb 500; one day old) were housed and distributed into a completely randomized design into six treatments (eight replicates; 30 animals per pen). To produce the experimental diets, three types of performance enhancer additives were used. Halquinol (HAL), avilamycin (AVI) and mannan oligosaccharides (MOS) were included (alone or in combination) in the basal diet (instead of corn starch). Effects of diet were observed on results of animal performance in the period 1-21 and 1-42 days old. Broilers fed... |
